BAND-CUTTER AND FEEDER.

sota, have invented certain newand useful Improvements in Band-.Cuttersand Feeders;

and I do hereby declare the following to be a full, clear, and exactdescription ofthe invention, such as will enable others skilled in the:art to which it appertainsto make and use the same.

My present inventionI relates to band-eutters and feeders, and hasforits especial object to provide means whereby more ellieient movementsare given both to the cutter-bars and to the overhead feed-bars.

The invention consists of the novel devices and combinations of deviceshereinafter described, and defined in the claims. y

The invention is illustrated in the' accompanyiug drawings, wherein likecharactersim vdicate like parts throughout the several views.

Figure 1 is a view, partly in vertical section and partly in sideelevation, showing a portion of a tln'eshing-machine and a band-cutterand feeder, the latter embodying my invention. l plan and partly inhorizontal section and with some parts broken away and others removed,showing the cutter-bars, overhead feed-bars, and crank' for driving thesaine. Fig. 3 is a detail in side elevation,v with someparts broken awayand others sectioned approximately in the line w3 :c3 of Fig. 2, showingthe cutter-bars, overhead feed-bars, and supports for the same. Fig. 11lis a view corresponding to Fig. 3, but showingI the parts in differentpositions.

Of the parts of the threshing-machine or :separator proper the numeral 1indicates the case or inclosing frame, the numeral 2 thethreshing-cylinder, the numeral 3 the toothed concave, and the numeral 4the lower or unl der serrated feed-pan,which feedpan receives avibratory motion in the ordinary` or any suitable way by means lnotillustrated.

The numeral 5 indicates the hood of the band-cutteraud feeder frame,which hood, as is usual, connects with the separator-case 1in thevicinity of the cylinder 2.

` The numeral 6 indicates the feed-table, and the numeral 7 the endlessconveyor, which Fig. 2 is a detail view, partly inA -runs` over thevsame and delivers the uuthreshed lgrain onto the vibrating feed-pan 4of the separator.

.The numeral S indicates a transversely-extended crank-shaft mounted insuitable bearings 9 on the sides of the hood 5 and provided at one endwith a pulley l0, over which ay power-driven belt (not shown) runs toimpart motion to the said crank-shaft. p The cutterbars 11 are carriedby this crank-shaft S,`and, as shown, they are providedwith bearingboxes12, by means of wllich they are jourualed to the crank portions of saidshaft. At their forward ends the cutter-bars are pivotcd to thedepending free ends of links 13, the upper en'ds of which links arepivoted to suitable supports 14 on the hood 5.

The overhead serrated cutter-bars 15 are su pported at their forwardends from the hood 5 by links 16, and at their rear ends they areprovided with projecting metal straps 17, which are pivotally connectedat their rear ends to the cutter-bars 11,preferably to blocks orlugs 18,secured directly in front of their bearing-boxes The cutter-bars 11 are,as is usual, provided with a plurality of beveled knife-sections 1U.

It will be noted that the links 13 and 16 are each formed by a pair oflaterally-spaced straps. The extensions 17 of the overhead `feed-bars 15are also preferably aoi'ded by pairs of parallel straps which Workbetwee the straps of cooperating links 13.

Prior to my present invention it has been customaryI to rigidly connector integrally form the cutter-bars with the serrated overhead feed-bars,in which ease, of course, the intermediate links 13 have not beenemployed. I have found that more eiicent movements, both of thecutter-bars and of .the overhead. feed-bars, may be obtained by formingthem separate] y and pivotally eonnectin g the same, as illustrated inthe drawings.- Under the upward orreturn. movements of thev cutterbarsthe links 13 cause therear ends of said bars to rise higher and thentodescend more rapidly than in the priorarrangement noted; also, theoverhead feed-bars 15 are given an Aendwise movement more directly inthe direction of the line ot feed to the threshingcylinder.
